In other words, £1 in 1918 is equivalent in purchasing power to about £1.10 in 1919.

The 1918 inflation rate was 22.09%. The inflation rate in 1919 was 10.05%. The 1919 inflation rate is higher compared to the average inflation rate of 3.99% per year between 1919 and 2020.

Inflation rate is calculated by change in the composite price index (CPI). The CPI in 1919 was 21.90. It was 19.90 in the previous year, 1918. The difference in CPI between the years is used by the Office for National Statistics to officially determine inflation.

## How to Calculate Inflation Rate for £1, 1918 to 1919

Our calculations use the following inflation rate formula to calculate the change in value between 1918 and 1919:

CPI in 1919 CPI in 1918
×
1918 GBP value
=
1919 GBP value

Then plug in historical CPI values. The U.K. CPI was 19.9 in the year 1918 and 21.9 in 1919:

21.919.9
×
£1
=
£1.10

£1 in 1918 has the same "purchasing power" or "buying power" as £1.10 in 1919.

To get the total inflation rate for the 1 years between 1918 and 1919, we use the following formula:

CPI in 1919 - CPI in 1918CPI in 1918
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

21.9 - 19.919.9

=
10%

Politics and news often influence economic performance. Here's what was happening at the time:

• First recorded case of Spanish flu in Kansas, marking the beginning of a worldwide pandemic killing millions.
• The Bolshevik Party changes its name to the Communist Party.
• Moscow is declared the capital of Russia.
• Tsar Nicholas II of Russia is executed along with his family by a Bolshevik squad in Ekaterinburg.

## Data Source & Citation

Raw data for these calculations comes from the composite price index published by the UK Office for National Statistics (ONS). A composite index is created by combining price data from several different published sources, both official and unofficial. The Consumer Price Index, normally used to compute inflation, has only been tracked since 1988. All inflation calculations after 1988 use the Office for National Statistics' Consumer Price Index, except for 2017, which is based on The Bank of England's forecast.
